To replicate all the figures in the paper, you will need to proceed as follows:



Step 1. Change *.zip.data to *.zip and unzip the files.
All datasets are publicly accessible.
(1) NCEP Reanalysis (http://www.esrl.noaa.gov/psd/data/gridded/data.ncep.reanalysis.html)
(2) ERSST V4 (https://www.esrl.noaa.gov/psd/data/gridded/data.noaa.ersst.v4.html)
(3) AQS ozone (http://aqsdr1.epa.gov/aqsweb/aqstmp/airdata/download_files.html)

Step 2. Go to ./Figures and run the R scripts there.
